H*(As(K)) = H*(A-s(K)) for all sand
H*(As(K)) = Z for s ≥ m.The calculation of H*(As(K)) is done using the model for knot Floer complexes coming from grid diagrams; see , , , . In fact, the code is inspired from the program  for computing the usual knot Floer homology.

./ASHat "[4, 0, 1, 2, 3]" "[1, 2, 3, 4, 0]". This is the left-handed trefoil. The first list corresponds to X's and the second corresponds to O's. The origin of the grid is the lower left hand corner.
This means that for s=0 the homology is of rank 2 in relative grading 0
and rank 1 in relative grading 1. For s=1 (and in fact for any other
nonzero s) the homology is of rank 1.
